摘　　要：分别用提取变量积分法、正规乘积内的积分技术及投影算符转换法,得到了坐标表象中压缩算符的显式.The integral of the squeezing operator in the coordinate representation is obtained by extracting the variable from the projection operator, using the technique of integration within a normal product of operators and transforming the non-symmetric projection operator into symmetric, respectively.
